On the picture in the wiki it says PCIE3.0 1 lane for 4G/5G, but in the datasheet, it is PCIE2.0.

Is there a BSP? What part is open source and what part is not? Is there a detailed datasheet available?

This does not show up in https://forum.banana-pi.org/latest

This is interesting, it is based on kernel 6.6:

Commits · 981213/openwrt - sf21a6826_upstream

It also shows what needs to be upstreamed (if they ever do) for it to become mainline…

Hi,

I tested Banana Pi BPI-RV2 with OpenWrt (banana-pi release and OpenWrt Snapshot). It works very well, but I have some questions about USB and NVMe support.

  1. USB 2.0 Host

banana-pi OpenWrt USB 2.0 port works fine. USB device is detected and powered. OpenWrt snapshot USB 2.0 port does not work (all required modules enabled?), no power to USB stick, not detected.

Q: How to enable USB2 port properly with OpenWrt snapshot (via menuconfig / kernel_menuconfig / dts) ? Edit: A: Banana Pi BPI-RV2 OpenWrt support - #2 by grrguu

  1. NVMe

banana-pi OpenWrt the NVMe module is not included ? NVMe does not get detected ? OpenWrt snapshot NVMe module is loaded, but NVMe does not get detected ?

Q: How to enable NVMe support with OpenWrt snapshot ?

What is the function of the M2 voltage jumper ? Is there any documentation what it does ?

Thank you for your help!
